Returns the element-wise max of two SparseTensors.

Assumes the two SparseTensors have the same shape, i.e., no broadcasting.

a_indices A Tensor of type int64. 2-D. N x R matrix with the indices of non-empty values in a SparseTensor, in the canonical lexicographic ordering.
a_values A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, int64, bfloat16, uint16, half, uint32, uint64. 1-D. N non-empty values corresponding to a_indices.
a_shape A Tensor of type int64. 1-D. Shape of the input SparseTensor.
b_indices A Tensor of type int64. counterpart to a_indices for the other operand.
b_values A Tensor. Must have the same type as a_values. counterpart to a_values for the other operand; must be of the same dtype.
b_shape A Tensor of type int64. counterpart to a_shape for the other operand; the two shapes must be equal.
